Dealing with Damp & Waterproofing in Tenerife Properties
By TruTrade Team
Understanding Damp in Tenerife
Despite its sunny reputation, Tenerife has significant humidity issues, especially in northern areas and coastal properties. Damp can cause health problems, structural damage, and costly repairs if not addressed.
Types of Damp
Rising damp: Moisture rises from the ground through walls. Common in older properties without proper damp-proof courses. Signs: tide marks on walls, peeling paint, salt deposits.
Condensation: The most common type. Warm, moist air meets cold surfaces, creating water droplets. Worse in winter when windows are closed. Signs: mold on walls, foggy windows, musty smell.
Penetrating damp: Water enters through walls, roofs, or windows. Common after heavy rain or due to poor maintenance. Signs: damp patches that appear after rain, water stains.
Solutions
Ventilation: The simplest and most effective solution for condensation:
- Install extractor fans in bathrooms and kitchens
- Use dehumidifiers in problem rooms
- Open windows regularly for cross-ventilation
- Consider a whole-house ventilation system
Waterproofing: For structural damp issues:
- External wall waterproofing: €30-60/m²
- Roof waterproofing: €20-40/m²
- Damp-proof course injection: €50-100 per linear meter
- Terrace waterproofing: €25-50/m²
Mold treatment: Professional mold removal and anti-fungal treatment: €200-800 depending on area affected.
Prevention
- Maintain gutters and downpipes
- Seal around windows and doors
- Ensure proper drainage around the property
- Fix roof tiles promptly
- Ventilate, ventilate, ventilate
